Astro is the God of the celestial plane and unconsciousness.

• Primordial God
• Bigger than planets and galaxies, a smidge bigger than the other gods as he is Primordial.
• Being a Primordial God, Astro is able to create realms in which only he and Dandy can enter, unless another figure is given access. One example of the realms he has created is the place where he and Dandy usually settle marital disputes and others in order to avoid accidentally damaging or destroying universes and such. Astro is a gentle, caring, and loving toon. However, he is sometimes prone to curiosity taking hold of his actions, resulting in two mortal affairs that he regretted having. His face resembles a crescent blue moon. The dark side of the "moon" is the right side of his face. He does not have eyes on this part— Instead, there is a figure of a compass on that black side of his face. The right side of his face is normal, and he has one eye— and another smaller one right below his normal eye. He has purple eyeshadow, one of his children's doings. His skin is light blue, and his upper body has crater patterns. His insides are all a dark blue, implied by his mouth's color. He has slightly sharp teeth. He has four arms. His legs and arms fade into a deeper blue. Astro wears a long, purple cloak that reached and covered his feet, the color fading darker nearing the edge, with patterns of constellations on that darker part. He wears a deep purple opaque veil with a gold trim pattern. Six different moons surround his coat. At the top of his head are smaller figures resembling the planets in the solar system of Earth. His mortal disguise is smaller, containing aquatic features.

He is married to Dandy— The God of the material plane and consciousness. He has had two mortal affairs, one child from his first, and two in his second. He has two children with Dandy. He also has a shared 'pet' with Dandy, the guardian of worlds. Pebble is primordial, however, he, being a rock-dog of sorts, cannot create realms. He is made of moon-rock. Pebble has the ability to run through time and space, and to bury galaxies and hide them from Astro's radar. Astro doesn't like when Pebble hides galaxies from him, but cannot stay mad at Pebble, even if Pebble treats planets like toys and has accidentally destroyed planets before. He cherishes them all. His first affair-child is Finn Novalite, demigod of the seven seas. Deceased. However, Astro can still visit him in the afterlife. His second affair-child is Poppy Novalite, demigoddess of essence. Alive. His third affair-child is Poppy's sibling, Glisten Novalite, demigod of perception. Alive.

His child with Dandy is Cosmo Novalite, god of mortal goods. Alive, married to Sprout Fossilian, God of Harvest, son of Shelly Fossilian, the Goddess of Earth and Organic life.

Cosmo, Astro's first child with Dandy came to be when he first tried the to cook/bake to test the concept of it, making a swiss roll. Dandy was skeptical and instead gave it life, creating Cosmo, the god of mortal goods. Connie, Astro's second child with Dandy was born from an attempt to rebuild a dead star, giving her a ghost-like form. She is the overseer of the afterlife.

Despite having had two mortal affairs, Astro deeply regretted his decision and has since gotten on better terms with his husband, Dandy. Both cherish, love, and adore eachother deeply.
